The stem-and-leaf plot below shows the number of pages each student in the class read the previous evening.

A stem and leaf plot showing the pounds of food collected is shown.
The stems from top to bottom are 0, 1, 2, 3, 4, 5.
The first column of leaves is 5, 2, 2, 3, 2, 7.
The second column of leaves is 0, 3, 4, 5, 4, blank.
The third column of leaves is 5, 5, 6, 6, 6, blank.
The fourth column of leaves is 8, 8, 7, blank, blank, blank.
The fifth column of leaves is blank, 8, 7, blank, blank, blank.
The sixth column of leaves is blank, 9, 7, blank, blank, blank.

According to the plot, 75% of students read less than
13 pages.
33 pages.
35 pages.
46 pages.

The stem-leaf plot is attached below

According to the plot, 75% of students read less than 35 pages ⇒ 3rd answer

Step-by-step explanation:

At first lets count the number of the students from the picture

There are 4 students in the 1st row

There are 6 students in the 2nd row

There are 6 students in the 3rd row

There are 3 students in the 4th row

There are 3 students in the 5th row

There are 1 student in the 6th row

The total number of students = 4 + 6 + 6 + 3 + 3 + 1 = 23

Let us find 75% of them equals how many students

75% × 23 = × 23 = 17.25

That means 75% of the students is about 17 students

Let us find the 17th student read how many pages

From the chart the 17th students read 33 pages

The 18th student read 35 pages

So 75% of the students read less than 35 pager

According to the plot, 75% of students read less than 35 pages

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
